Hypothesis:
If the frequency of the waves are greater than it is likely the case that there will be less litter coming to the edges of the lake because if a wave passes through an object the object will not move but only go up and down. The actual force that moves the litter would be the wind (an external force), but we are not just considering the litter on the surface of the water but also the microrganisms and heavy metals that exist inside the water moved by the waves.
Research Question:
To what extent does the speed of the waves in Tay Ho (West Lake) affect the amount of litter in the two specified regions of the lake?
Variables:
Independent Variable: Area
Dependent Variable: Frequency
Controlled Variables: Wave Length and Time Period
